Definitions

  • a voltage applied to the piezoelectric element 3 has such a waveform as shown in FIG. 1A.
  • the voltage applied thereto is increased relatively gradually at a constant rate.
  • the voltage is lowered to a non-driving voltage level relatively quickly to restore the piezoelectric element 3 to the original state and to thus decrease the pressure in the ink chamber 4.
  • ink ejecting force is no longer applied to the ink but a mass of the ink which has been applied with the force is about to leave from the nozzle 5 due to its inertia and is finally ejected from the nozzle 5 to produce an ink droplet.
  • ink is supplemented into the ink chamber 4 from an ink tank (not shown) through an ink supply channel 7.
  • a first voltage is firstly applied to the piezoelectric element for causing the ink to be moved in the nozzle in a first direction so that the ink droplet is ejected from the nozzle.
  • a second voltage is subsequently applied to the piezoelectric element for causing the first directional movement of the in to be abruptly stopped.
  • a third voltage is applied to the piezoelectric element so that the ink does not move in a second direction opposite the first direction.
  • the first voltage changes from a non-driving voltage to a peak voltage (level b in Fig. 2A) at a first rate.
  • the non-driving voltage is defined by a voltage with which the piezoelectric element is not deformed.
